HEATING! DEVICE.

Applicationvmearbruary 15, 192s. semaine. 619,223.

To all whom t may concern Beit known that I,;JosnrH L. DoNA'r, a citizen ofthe UnitedStates, and a resident of the city of Chicago, in the county of @ook andStateof Illinois; have invented certain new and useful Improvements in a Heating Device; and I do hereby declare that the following is a full, clear.,andexact description of the same, reference being had to the accompanying drawings and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to heating devices, more particularly for household purposes.

It frequently happens that one or more of the rooms in a house are insufficiently heated. Moreover, it is often the case that a chimney passes through such room up which chimney a large amount of heat escapes.

One of the principal objects of the present invention is to provide means for utilizing a part of this heat which now goes to waste for heating the air in a room.

Another object of the invention is to provide means for varying the amount of heat transmitted from the chimney gases to the room.

A further object of the invention is to provide an improved form of radiator.

Other and further important objects of this invention will be apparent from the disclosures in the specification and draw ings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a side elevation of a heating device embodying the present improvements.

Figure 2 is a horizontal section on the line 2-2 of Figure 1.

Figure 3 is a vertical section on the line 3-3 of Figure 2.

As shown on the drawings:

An entire section' of the brick work 5 of the chimney is removed for the insertion in its place of the radiator. The radiator is preferably formed, as shown, of four identical sections 6, each having four walls, one, 7, acting as the heat radiating surface, the inner wall 8 forming one side of a central flue 9 through the radiator, while the other two walls 10 contact with the corresponding walls on the adjacent sections. Along one edge'ofeachsection isarrangeda flange l1 adapted to'enter a correspondingk recess vin the adjacent section. With this construction apairfofscrews 12 through each {iange serve to hold the-sections securely together.

A further advantage of the construction shown is that each section is exactly similar to Vall the others, thus facilitating not only manufacture buty alsoy replacement of a section which may have become cracked or broken.

The walls 8 forming the central flue 9 are cut away at the bottom at 13 and at the top at 14 to allow heated gases from the chimney to pass through the passage 15 in each of the sections. The central flue 9 is in substantial register with the passage through the adjacent sections of the chimney so that normally the hot gases will pass chieily through the flue 9 and only to a very limited extent through the passages 15. Under such circumstances little heat will be radiated into the room. To increase the flow of gases through the passages 15, a damper 16 is provided in the central flue 9. This damper is mounted upon a bar 17 journalled in the walls 6 and 8 and provided with a handle 18 or the like by which its position may be adjusted. When the damper is closed all of the gases are compelled to flow through the passages 15.

As the sections are all made exactly alike, each wall 6 and 8 is provided with an aperture for the passage of the bar 17 of the damper, although of eight such apertures only three are actually used for this purpose. Accordingly the remaining five apertures may be closed by any suitable means, such as cement, screw plugs or the like.

The outer wall 6 of each section constitutes the heat radiating surface and to increase its effectiveness for this purpose it is intended to form a series of pyramids 19 which greatly increase the heat radiating surface. v

Around the radiator is a grid 20 which prevents a person from accidentally coming in contact with the highly heated surface of the radiator proper. y

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

A. A heating device adapted to replace an entire section of a chimney, a flue of shorter length than said section adapted to register with the chimney, radiators surrounding said flue, a damper in said flue adapted to control the flow of gases from the chimney around the lower end of the flue, up the outside of the flue and around the top of the ue into the chimney again.

2. A heating device comprising four inten locking sections forming a central flue, means for securing the sections together, each section including a passage Jfor heated gases, and a heat radiating surface.

3. A heating device comprising four interlocking sections forming a central flue, means for securing the sections together,

each section including an inner wall, an outer heat radiating wall, and a passage for heated gases therebetween, the inner wall of each section being cut away at both top and bottom to allow entry and exit of gases to and from said passage.

4f. A heat radiator adapted to replace an entire section of a chimney, said radiator including a central lue and a by-pass therearound, and means for controlling the flow of gases through the central flue.

In testimony whereof I have hereunto subscribed my name in the presence o two subscribing witnesses.
